R CMD check issues

[gvelasq]

Starting from the latest Travis build #35, there are several remaining items to address in R CMD check:

• [x] Warning: Several LaTeX errors with .Rd files ending in \end{description}, possibly because @description is meant to be the second paragraph of each documentation block. Lines:
  • L7090
  • L7100
  • L7113
  • L7128
  • L7150
  • L7160
• [x] Warning: Several LaTeX errors for 'Overfull \hbox'. Lines:
  • L7122
  • L7137
  • L7141
  • L7145
  • L7170
• [x] Error: Error in texi2dvi, unable to run ‘pdflatex’ on ‘Rd2.tex’
  • L7319 says ‘Error in running tools::texi2pdf(). Since L699 doesn’t list {tools} as an attached base package and it’s not listed on L825 as one of the 94 installed packages, we might need to add {tools} to .travis.yml.
• [x] Warning: Non-standard license specification, CCBY-4.0
• [x] Note: No visible global function definitions for several functions from L8360 to L8375
• [x] Note: Undefined global functions or variables from L8376 to L8378
• [x] Warning: Missing documentation entry for wt05_aggdat_merged_dat on L8386
• [x] Warning: Code/documentation mismatch for tt_tweets on L8394
• [x] Warning: ‘processed’ and ‘raw’ folders in the ‘data’ directory
  • Travis suggests moving these to ‘inst/extdata’
